Main Features:


1)Winner Patent -Optical path design

Converging light Fourier transform light patented technology, make scattering light not be restricted to lens aperture. Double spectrum design make its precision achieves from 0.01μm to 2000μm,and Dual-laser orthogonal light make use of the semiconductor auxiliary laser extend the test angle from 45 degree to 135 degree, ensure receive all the angles of signals.


2) Expand Size Range

 PTT-2008A measurement range significantly expanded to 0.01um, particularly suitable for small samples of the user, the sub micron particle test results reached the international level


 3)Full automatic built-in wet dispersion system

The ultrasonic dispersion, mechanical stirring and circulation channel reasonable integrated in the interior of the instruments, ensure the uniform dispersion and distribution of particles in the testing process, effectively avoid uneven distribution, large particle deposition phenomenon caused by long pipe line of outside dispersion system , to ensure the accuracy of the test results.


4) Intelligent Operation mode

 With intelligent automatic mode of operation, to achieve a key test, as long as according to the prompt addition of sample, click the "test", all processes including water-supply, dispersion, circulation, testing, cleaning, data record, data analysis, save and print are automatically completed, not only reduce the testing workload, but also eliminate the interference of human factors, to further improve the accuracy and authenticity of testing results.


5)Automatic Optical path alignment system


The precision of four hybrid stepping motor in the automatic system of optical components, micro precision of 0.1um, the instrument of light path is always at its best to eliminate manually on the light path and the troubles and difficulties but also enhance the accuracy and stability of test results.



6)Authoritative calibration method

 In the entire test range using the national standard materials for calibration, only a year calibration once the instrument can. Calibration method is simple and quick.


7) Unconstrained free fitting patent technique


Winner original unconstrained free fitting patent technology, particle size analysis is not affected by any functional constraints, truely refelect particle size distribution.
